ciprocating movement in a head 16 of the frame, the lower end of the plunger having*l a hole wlthin whicha receiving pin 25v isl rivets or eyelets, 4by means of which `the disks are secured in` place, said pin being seated against a spring .(not shown) in the bottoni ot the hole inspring and pin lbeing held in place in any pivotally securedv to a plunger operating bar otally mounted in the base is connected by a rod23 with the bel-l ciank lever 21 as ameans i 15 'located with its lower endat-adistance fromV for operating the piunger. A chute 24 is the plunger, and the @5 suitable manner. A ro'ck shaft 17 is mounted in the head 16, and links 18, 19 extending Afrom said shaft and plunger respectivelyr are the anvil 13, and in 'position Ato deliver the" Veyelets or-'hollow rivets-inthe'path oftravelf' of the pin 25, by which, in thefinovement of :the plunger, the eyelets aredelivered on to the pin la. The chute 24 isormed as an extension from ajrockingho'pper member'26 i mounted onl a shaft-ejxtending itrom1 the` frame. .A rotating. hoppen-.member 28 .is

also supported on the shaft' 27,* the members 26 and 28 containing a chambervforming a hopper vopening'to the passage Way-inthe -ichute 24;. The'x'nember 26 isrocke'd Ain a -well known manner by connection with the' plunger and tl-nls moves the lower end ot' .the chute out of the path of movementA of the plunger at the proper time, anda ratchet `mechanism 29- is employed to'rotate the I member 2 8 in a manner well known. A spring actuated holding bar 30 operates to retain' the chute in its backward position away from the plunger until released at the propertime as by movementof the plunger. All the parts herein before described are of old and well known construction and further and detailed description is therefore omitted y herein.

ln aiiiXing disks to envelops 'by means heretoitme employed, the rivets have been 'supplied and fastened by fa'machine sin-ilar to that herein above described, the disks having been manually placedin position in the machine, and the disks that secure the cord permanently having had such cordaffixed-thereto before the disks were separately notes a disk magazine or tube in which disks 32 are located one upon another', the lower end of this tube resting upon a table 33.y This table is secured to the fr aine F, projecting forwardly therefrom underneath the head 16, and a groove 34 is formed undisk carrier 3 5 pivotally secured to the underside of the table and having a sl't to receive a stop pin 36 projecting from the underside of the table. This carrier has a lippedL recess 37 into which and upon the lips of which the disks 32 move, one at a time,'the distance between the upper surface fof the lips and the upper surface of the carrier being substantially equal to the thickness of the disks. A carrierbar 38 is pivotally attached to 'the carrier (as 'shown j herein) to a plate 39 rigidly secured to the- "arrier, and to a bell crank lever40 pivotally lmounted on the frame. This'- bell -crank lever has a pin projecting into a slot 43 at one end of a carrier operating rod 41 and a spring 42 forces the pin to that end of the slot away from the connection'of the rod with the bell crank lever 21, which connection is also by means of a pin on the lever engaging a slot 95 in the upper end' of the rod 41, a spring 44 exerting force upon the rod in the same direction as the spring'42.

This will cause the parts to assume the normal position sliown in Fig. 1 in the drawings, with the recess 37 in the disk carrier underneath the plunger.

A carrier holder 45 is pivotally mountedon the frame with its hooked end in position to engage a holding pin 46 rising from the carrier (as shown herein from the plate 39) When said carrier is at the backward limit of its movement, and retain it in this position until the holder is released by the movement of a holder releasing lever 47 pivotally mounted on the frame with one end in position to engage the holder and the other end in the pathof movement of the pin 48 constituting the pivotal connectionbetween the operating bar 20 and the bell crank lever 21.

. A string controller disk 50 and a measuring disk 49 are rotatably mounted on the baseBgand arev arranged to vrotate together,

the'measuring disk being adapted to receive the string or twine 51I extending from a spool 52, or other source of supply, to the mechanism-for utilizing the string. -This string will be so engaged with the measuring disk that its movement wiill be controlled by the saikizv disk, in the structure herein shown the twine being wrapped one or more times about the disk, as may be desired. A pawl supporting arm 53, pivotally mounted, preferably'on thel stud supporting the controller and measuring disks,y supports a stop pawl 54 and a disk moving pawl 55, the latter pawl being pivotally mounted on a finger extending from the arm 53 and rigidly connected with the pawl 54. The moving pawl is arranged to engage a notch 5G in the controller disk and the stop pawl to engage a stop 57, herein shown projecting from the edge of said disk. A spring 58 is employed `to hold thedisk moving pawl against the derneath the table to receive the edge of a disk, and a pin 59 forming the pivot for the pawl is extended into the path of movement of a cam 60 located at the end of a swinging cam lever 61. This lever is pivotally supported on a movablepart of the mechanism, as herein shown` on an actuating rod 62 connected with the string placing mechanism, and a spring G3 holds the cam lever normally against a stop 64.

The actuating rod 62 extends from the treadle 22 to a string placing lever 65 pivotally secured underneath a ange 6G of the frame F.- A cam post 67 is rigidly secured to the lever and has at its upper end a hook actuating cam G8 located in position to engage a cam pin G9 projecting from the side of a'string hook bar 70 bearing string hooks 7l. The bar 70 is pivotally mounted at the upper end of a bar supporting post 72 and on a rod 73 projecting therefrom, said post being pivotally supported by the lever (i5 so that it may be rocked back and forth on said pivot. A knife 74 is secured at the end of a knife support 75 pivotally mounted on a bracket 76 secured tothe frame, this knife supporthaving a stud 77 resting against the upper surface of the hooks and held against the hooks by a spring 78. A string bar actuating stud 79 projects from the side of the string hook bar into the path ot movement of the back of the cam GS. A string guide 80 is secured to the bracket 7G and another string guide 81 Ls located on the opposite side of the ja-iv 12 from the first inentioned guide, the guide 81 having,r a notch 82 within which the string may be'placed Aand from which it may be readily removed.

A string carrier 83 is carried at the end 12 of. a string carrying arm 84, this carrier being tubular to receive the string and having an opening in which a string stop or detent 85 projects, this stop being in the form of a spring which will permit the string to 12 mounted in the bracket, a block S6 being se- 13 placing it inthe notch 82 in the string gulde Gilijrldifgthe opposite end ofthe pivot.. A

carrier actuating rod 87 is pivotally streng' l 4attac edat 'one end to' said blockv and its oppositegend is pivotally connected,.by a pin -andslet 'monnectiomfwith the bell crank lever 21;:38 being' the' pin and'89the slot.

spring: 90 holds the actuating rod 87 in i dle, the operati vey grasps the end ofthe string projecting through theA carrier .83 Vand eX- tends vit across the-,iront of the machine,

81 and extending it beyond the guide as far as permitted by the .measuring device'.

rEhe parts being in the positions shown in the drawings, the treadle having vbeen operateddto move thev lever 21 to carry the pin 48 to the bottom of the slot 95,'a continued,l pressure 'upon the treadle 22 .rocks th'ebell crank ylever 21 further, actuating the plun ger 15 through the'mediumof the links andv bars 18, 9, and 20, ystarting the plunger in v its downward Jr'novememi--` v v The lower' end of the chute 214 resting normally underneath the plunger, a hollow rivet is in positiontoreceive the pin 25, and the disk earrier 35 also resting normally under# neath .the plunger, a' disk 32 is located 'in the path. et movement of the pin 25. i As the-.plunger moves downward, the pin 25 p'assee 'intothe hole-'in a rivet, immediately afterwhich, lthe-vehute 24 is j moved l from under' theplunger in av manner com'- 'mon .tov prior machines; The. continued pendently, of the carrier, this to 'permit' movement of the plunger, if required', yafter engagement of thepin 36 with the end vor' its slot, when the carrier holder engages the holding pin 446, retaining the carrier in this position for a limited time. In this position of the carrier the bottom disk 32 in the magazine 3l drops into the recess 37 ready to be moved forward bythe carrier.

The, movement of the treadle 22, as above described, operates, by means of the connecting rod 23, the 'string carrier actuat-fr ing rod 87 the pin and 'slot connection 88, 89 permitting an initial movement'o'f the plunger before operation -of, the string carrier.; rll`his operation of the rod 87 rocks the block 86 and the string carrying arm 84,

and at the 'proper time the string, which has beenentended across they frontof the machine, is carried' downward in close proximity to or against the front of the pin 14.

i As the treatlle is pushed downwardcarrytensioning the spring 63 and permitting the cam to pass the pin.

lryjthis downward movement of the bar 62, as hereinbeforeV described, the'cam 68 is swung backwardly, permittingthe string.

hooks to; drop, under the induence of the knife ysupport spring 78, in position to enf` gage the string which has been extended, as

hereinbefore described.A The cam 68 in` its continued movement strikes withL its back against the string actuating bar stud `79 movingfthe supporting post 72 backward, carrying with it the lstring hooks 71 which, engaging the string, wrap vit partially about the rivet under the washer. The continued".

movement 'of the plunger turns over the end filiv ing with it thqe actuating rod 62, thecain strikes lthe pin 59 swinging the ,lever "61,

o'the rivet, in a. manner wellknownysecuring the washer and string firmly in place, the string between the washer and envelop. The backward movement of 'the hooks 71 movement oftheplunger. carries theholllow 45 rivetthrough. a positioned. disk 1n' 'the carcarries the string against 'the knife, sever 110 60 sprin 42 being sucient to cause this opernotedthat the pin .48 movesin thel slot 95 rier 35,' and before the vshrmlder at the base. of the pin v25 .strikes the disk the .carrier is moved'backward from under the plunger, leaving the diskA upon the rivet .and the latteruponthe pin.- l 1 In the operationofthe carrier, itwillba ation" an`d-to swing the carrier backward untilthe stop 36"engages the end of its slot. Expansion of the spring 42 will now permlt the rod 41 to have afurther movement, indeing 'it from thelength extending. from the spool.

As pressure on the treadle is'released the l spring 92 carries the ,treadle upward reversingthe movement dit' the parts.

As the bell crank lever 21 swings in the reverse direction, the prings 42 and 44 carry the lever 41 ywit out movement of the bell crank 40, the slot and pin connection permitting this movement and thus lallowing the carrier 35 to remain at the backward limit of its play for a certain period As the bell crank lever 21 is thus moved backwardly the pin 48 strikes the releasing mem,- ber 47, at about the completionvof the move; ment of the bell crank lever, rocking the carrier holder 45, disengaging it from the pin i 46 and permitting the carrler to swing to its normal position under the pull of the spring 44, -a retainer QS'engaging the washer inthe lac . Striking the projection 94 at the upper end of the cam post, carries the hooks forward to their normal position of rest.

As the rod 62 moves upward the cam 60 engages the pin 59, and, being obliquly dis,

posed with respect to its path of movement, swings the stop pawl on its pivot and carries its end outof the path of movement of the stop 57. The disk moving pawl will normally rest with its end a short distance from g the shoulder formed-by the notch 56, as

shown in Fig. 1.0i the drawings, so that the movement of the parts above described, andv suiii'cient to enable the stop pawl to be moved out of the path of movement of the stop, is permitted, and a continuation of the movement, caused by the cam 60, for a slight distance carries the stop 57 underneath the end of the stop pawl V54: that now rests upon said stop. -The measuring device is thus left, at the completion of an operation by the ma chine, in condition to permit the running out of the string to the proper length, the controller disk, in this operation, making substantially a complete rotation, at the colnpletion of which, the stop 57 engages the end of the pawl 54, that has resumed its location in the path of movement of the stop immediately upon disengagement of the cam 60 from the pin 59. The measuring disk 50 will be of a size to permit feed of the desired length of string in a single rotation of the measuring disk, which is permitted by the construction of parts above described.
